Piher sensing systems - custom potentiometers and position sensors

Through-shaft sensing

Original thinking

Design engineers of rugged applications want all the benefits of contactless rotary sensing (no wear and tear) without expensive overengineered solutions to precision. They want enough accuracy plus stable performance over a long lifetime, despite environmental extremes. At Piher you will find fully customized, semi-custom, and off-the-shelf sensors, all featuring truly non-contacting operation.

Piher’s novel through-shaft sensor effectively wraps around any shaft, sensing directly at source. One slimline 9mm package contains two non-contacting components—a full-circle magnet and electronics module.
+ Application-patented design can be fitted anywhere on a shaft, giving engineers the flexibility to be creative.
+ Cost effective as opposed to expensive optical or inductive angle sensors.
+ Easy-to-assemble, so production line costs are less than those of other sensor solutions.
+ No maintenance needed over the product’s life.
+ Delivers the same level of 360-degree precision and stability over at least 50 million rotational cycles as the day of installation—despite extremes of vibration, shock, temperature and contamination.
